I have been given different due dates....the 9th of august, the 12th of august and the 15th of august, the 15th was my first date given. my first u/s on january 2nd said i was 8 weeks and 1 day pregnant. My lmp was october 28th approx. i had it on halloween for sure and the first few days of november. my period before that was sept. 21st, so my period was a week late. my bf and I had broken up and i ended up sleeping with an old friend from my old town when we were drunk. that was on november 6th. my ex and I got back together a week or so after that and we had sex every day or every other day after we got back together. based on the dates given when did i conceive....is it possible it could be my old friends?? can you get pregnant a couple days after your period ends?? i'm so confused and feel horrible and need to know what the chances are. please help!
